You enter the cave through the gift shop (nice technique) and explore about one mile of the cave with a guide for forty-five minutes. It’s pretty cold and wet down there (in the '50s) so make sure you wear a jacket and shoes you don’t care about. After I got over my fear of the earth falling on me, I was able to enjoy some pretty beautiful formations. The best part is the wedding chapel. Yes, you can get married down here if you want to (seven couples already have). Admission is $12.
